1) “iHeartRadio Music Awards,” 8-10 p.m., Fox. Amid a sports surge, we also get pop music. Performers are Ludacris, who hosts, and John Mellencamp (shown here), who gets a special award, plus Alex Warren, Kehlani, Raye, Lainey Wilson and, for the first time, a linking of three classic girl groups — TLC. En Vogue and Salt-N-Pepa. Also getting a special award is Miley Cyrus.
2) Baseball, NBC. It’s opening day, a grand baseball tradition. There was one game (Yankees-Giants) Wednesday and three wait for Friday, but that leaves 11 openers today, including two on NBC and Peacock. It’s Pirates-Mets at 1:15 p.m., ET and Diamondbacks-Dodgers at 8:30.
3) Basketball. The second weekend of the college tournament starts with two teams that have pulled major upsets: Texas (seeded No. 11 in its region) faces Purdue (No. 2), at 7:10 p.m. ET on CBS; Iowa (No. 9) faces Nebraska (No. 4), at 7:30 on TBS. Then CBS has Arkansas-Arizona at about 9:45; TBS has Illinois-Houston at about 10:05.
4) “Love Story: John F. Kennedy and Carolyn Bessette” finale, 9 p.m., FX, rerunning at 10:15. This has been an excellent mini-series, with newcomer Paul Anthony Kelly as John and Sarah Pidgeon superb as Carolyn. We see the strain of public attention continue; then, on a cloudy day, John tries to solo-pilot his plane to his cousin’s wedding.
5) ALSO: “Love Overboard” — a sexy-singles reality show set on a ship — debuts on Hulu. (On Sunday, ABC aired the opener, which was before the lusty parts could take over. Also, there are gems from two masterful directors: Alfred Hitchcock’s “Psycho” (1960) is 8 p.m. ET on Turner Classic Movies; Spike Lee’s “Malcolm X”(1992) is 8 on MGM+.
